I agree with you, there is evidence, in your own words, "suggest" there is more at work than free choice.
But then, basing public policy on mere "suggestions" is pure folly, and bears no resemblance to science. That is corrupt political dishonesty, and that is what I condemn.
Perhaps the tender ministrations of wierd uncle harry produce statistically significant differences in brain function.
Perhaps evidence suggesting that such differences in brain function exist is in error, perhaps these statistically significant differences depend more upon fators unrelated or indirectly related to sexual preference, it is this cloud of uncertainty that REAL science deals with in creating a factual basis upon which ethical people can base their political and societal opinons.
It is amusing that you agree with me in substance but adhere still to the opposing view in the final instance.
